# exit=1 means git grep found no match. exit=0 means at least one match.

## C. DeliveryContext: test-only outside the leaf
src/messaging/messaging-kafka/src/test/java/dev/caskeleton/messaging/kafka/KafkaContractHarness.java:7:import dev.caskeleton.messaging.api.delivery.DeliveryContext;
src/messaging/messaging-kafka/src/test/java/dev/caskeleton/messaging/kafka/KafkaContractHarness.java:216:        new DeliveryContext(Instant.parse("2026-08-10T09:15:30Z"), false, "order-projection"));
src/messaging/messaging-policy/src/test/java/dev/caskeleton/messaging/policy/DeadLetterOrchestratorTest.java:12:import dev.caskeleton.messaging.api.delivery.DeliveryContext;
src/messaging/messaging-policy/src/test/java/dev/caskeleton/messaging/policy/DeadLetterOrchestratorTest.java:226:        new DeliveryContext(Instant.parse("2026-08-10T09:15:35Z"), false, "order-projection"));
exit=0

## D. the three competing handler contracts
src/messaging/messaging-core-api/src/main/java/dev/caskeleton/messaging/api/delivery/BatchMessageHandler.java:15:public interface BatchMessageHandler<T> {
src/messaging/messaging-core-api/src/main/java/dev/caskeleton/messaging/api/delivery/MessageHandler.java:14:public interface MessageHandler<T> {
src/messaging/messaging-core-api/src/main/java/dev/caskeleton/messaging/api/settlement/ManualMessageHandler.java:15:public interface ManualMessageHandler<T> {
src/messaging/messaging-reliability-api/src/main/java/dev/caskeleton/messaging/reliability/IdempotentMessageHandler.java:21:public interface IdempotentMessageHandler<T> {
--- what the only wired delivery processor actually accepts ---
40:  private final Function<MessageEnvelope<EncodedMessage>, HandleResult> handler;
47:      Function<MessageEnvelope<EncodedMessage>, HandleResult> handler,

## E. batch metadata is built, the batch delivery it describes is never assembled
src/messaging/messaging-kafka/src/main/java/dev/caskeleton/messaging/kafka/KafkaBatchConsumerRegistrar.java:104:    return new BatchDeliveryMetadata(
src/messaging/messaging-rabbit/src/main/java/dev/caskeleton/messaging/rabbit/RabbitBatchConsumerRegistrar.java:139:        new BatchDeliveryMetadata(
--- javadoc claiming a handoff ---
src/messaging/messaging-kafka/src/main/java/dev/caskeleton/messaging/kafka/KafkaBatchConsumerRegistrar.java:118:   * @param metadata the batch-wide metadata handed to the handler
src/messaging/messaging-rabbit/src/main/java/dev/caskeleton/messaging/rabbit/RabbitBatchConsumerRegistrar.java:153:   * @param metadata the batch-wide metadata handed to the handler
--- any construction of BatchMessageDelivery anywhere ---
exit=1

## F. leaf has no framework dependency (12.2 sibling comparison is not applicable)
spring annotations in leaf: exit=1
non-java imports in leaf main:
(empty above means: JDK plus own package only)
build.gradle dependencies block:
apply plugin: 'java-library'
